Abstract

Shape memory alloys(SMA) due to the exhibition of certain performance such as high damping, shape memory effects and Super-elasticity are consider for application in engineering systems.In this study, considering the usage of composite-sandwich structures in various industries including aerospace, the effects of SMA parameters such as SMA volume fraction and SMA wires temperature on hybrid SANDWICH PANEL free vibrations with transverse flexible core have been surveyed. The SMA wires (NiTiNol) are embedded at the mid-plane of the sandwich face sheets. For analyze, the IMPROVED HIGH ORDER THEORY is applied, First Shear Deformation Theory (FSDT) at the composite face sheets and Elasticity Theory by the assumption of inertia forces at the core. For governing equations of simply support panel Hamiltonian method has been used. At this study it is assumed that the SMA recovery stress produced via temperature actuation is exerted tensely on mid-plane of the face sheets. For solving problem and simplification the Galerkine method is used. The results showed that SMA actuation improves the vibration behaviors of whole SANDWICH PANEL.
